Аннотация
BACKGROUND: Tannerella forsythia is a gram-negative anaerobic bacterium commonly found in the oral cavity. It is among the common pathogenic bacteria associated with gingivitis, chronic periodontitis, and aggressive periodontitis. However, there is currently no literature discussing lung abscesses primarily caused by T. forsythia infection.
PRESENTATION: This article presents the case of a 55-year-old male with a massive lung abscess. The patient underwent ultrasound-guided percutaneous drainage, and the sample was sent for pathogen metagenomic next-generation sequencing (mNGS) testing. The test indicated that the lung abscess was primarily caused by T. forsythia infection. A literature review was conducted to understand the characteristics of this pathogen as well as its clinical features and suitable treatment approaches.
CONCLUSION: Currently, there is no literature specifically mentioning T. forsythia as a primary pathogen causing lung abscesses. This anaerobic bacterium is commonly found in the oral cavity and is difficult to cultivate using routine culture methods. mNGS emerges as a value diagnostic method for identifying this pathogen. Treatment recommendations include drainage and antibiotic selection encompassing common periodontal pathogens such as red complex bacteria and Actinomyces.
